BunkerWeb: Open Source WAF Sparks Privacy and Performance Debate in Tech Community

The emergence of BunkerWeb, a next-generation open-source Web Application Firewall (WAF), has ignited discussions within the tech community about the balance between security features and privacy concerns. As organizations seek robust protection for their web applications, the community's response highlights both enthusiasm for open-source security solutions and careful scrutiny of their implementation.

Key Features:

  • HTTPS support with Let's Encrypt automation
  • ModSecurity WAF with OWASP Core Rule Set
  • Automatic security patches and updates
  • Bot and bad IP blocking
  • Custom NGINX configurations support
  • Optional threatmap and crowdsourced security data

Privacy Concerns vs. Security Benefits

The introduction of BunkerWeb's threatmap feature has sparked a debate about data privacy. While the feature provides valuable threat intelligence through crowdsourcing, some community members have expressed concerns about the telemetry aspects. A BunkerWeb representative clarified that the BunkerNet feature is entirely optional, allowing users to maintain privacy while potentially sacrificing access to crowdsourced threat data.

Enterprises pay a shitload of cash for that functionality of commercial WAF systems. Some allow that at a low let cost if you send your own data, and more expensive if you don't.

Performance Considerations

Performance impact has emerged as a key discussion point among potential users. When compared to a standard NGINX installation, BunkerWeb's implementation of security features through LUA modules does introduce some overhead. The development team acknowledges this trade-off, noting that performance impact varies based on enabled features, allowing users to fine-tune their security-performance balance.

Integration and Migration

For organizations with existing NGINX configurations, BunkerWeb requires a complete migration rather than parallel integration. However, its NGINX foundation and support for custom configurations make the transition more manageable. The platform offers compatibility with multiple domains, server and client certificates, websockets, and custom settings, though users need to adapt their existing setups to the BunkerWeb framework.

Deployment Options:

  • BunkerWeb Cloud (SaaS)
  • Docker containers (x64, x86, armv7, arm64)
  • Self-hosted installation

Open Core Business Model

BunkerWeb has adopted an open-core model, with its base version released under the AGPL license while maintaining proprietary PRO features. This approach has generated discussion about the balance between commercialization and open-source security accessibility. While core security features remain available to all users, advanced features and technical support are reserved for PRO version subscribers.

Future Development

The community has already begun shaping BunkerWeb's development roadmap, with requests for features such as TLS fingerprint-based blocking (JA3) being acknowledged by the development team. This collaborative approach to feature development demonstrates the project's commitment to addressing user needs while maintaining security standards.

In conclusion, BunkerWeb represents a significant addition to the open-source security landscape, though its adoption decisions require careful consideration of privacy, performance, and integration requirements. Organizations must weigh these factors against their specific security needs and resource constraints.
